EYELETING-MACHINE.

Specification o Letters Patent.

Patented Jan. 5, 1909.

Continuation of application filed April 22, 1902, Serial No. 104,109.This application filed July 11, 1903. Serial No. 165,084.

To all whom it may concern:

Be it known that I, `GEORGE KNIGHT, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented an Improvement in Eyeleting-Machines, ofwhich the following description, in connection with the accompanyingdrawings, is aspecification, like letters on the drawings representinglike parts.

This invention has for its object the production of a novel eyeletingmachine.

My invention is illustrated in a machine for setting a plurality ofeyelets of each cycle of o eration of the machine.

I eretofore a plunger contained in one of the pair of sets has been usedto pick off from a raceway an eyelet to be set, and punched stock havingbeen put on the plunger, the set has been moved to set the eyelet. So,also, an eyelet has been put by hand upon a plunger, and the plungerholding the eyelet has been moved to co-act with a hollow punch to puncha hole through the stock, and the sets have thereafter been operated toinsert an eyelet in the unched hole, and upset the eyelet in said ho e.

In seeking to improve the eiliciency of eyeleting machines, I havedevised a machine comprising a series of top and bottom sets, a plunger,and a punch, said plunger and punch normally occupying a position in thesame vertical plane. The plunger is actuated to enter the eyelet at theend of a raceway, and take the eyelet therefrom, after Vwhich theplunger holding the eyelet rises toward the punch and upper set. l Theplunger holding the eyelet is so shaped .as to coact with an edge of thepunch, and

out a hole in the stock, and thereafter as the sets are actuated theyforce the eyelets from the plungers into the stock, delivering theeyelets about the unch, and thereafter the sets acting in usualpmannerset the eyelets in the stock.

The end of the plunger is shaped to present a rounded projection risingfrom a shoulder, said projection as theplunger rises entering unerringlythe endmost eyelet of the plurality of rows of eyelets at the deliveryend of the raceway, after which the raceway is moved leaving the eyeletssurrounding the plunger, the heads of the eyelets resting against the uper end of the lower or hollow sets. After the rounded ends of theplungers enter the eyelet, as stated, the plungers are further movedcausing said rounded projections to enter the holes in the punches thuscentering the plungers with relation to the punches, the movement of theplungers being continued until the shoulders of the plungers at the baseof the rounded projections co-acting with the cutting edges of thepunches cut holes in the stock to be entered by the eyelet. The diameterof the shouldersat the base of said projections is substantially aslarge as the external diameter of the punch, the plun er consequentlyacting as a guide for the eye et as it is being forced therefrom by thelower set to surround the punch prior to and during the process ofupsetting the eyelet in the stock.

In the machine in which I have represented my invention to set aplurality of eyelets at one and the same cycle of operation, theplungers and lower sets are moved in different times to perform theresults required of them.

The invention to be herein described and claimed is not, however,limited to the eXact shape shown for the said rounded extremity or theprojection that enters and picks 0H the eyelet from the raceway, as thesame may be varied to effect the result herein aimed at and yet notdepart from my invention that I intend to claim broadly.

Figure 1 of the drawing represents in front elevation, partially brokenout, a sufficient portion of an eyeleting machine to enable my inventionto be understood; Fig. 2 is a side elevation of the parts shown in fulllines in Fig. 1 looking toward the left of the drawing; Fig. 3 is adetail broken out to illustrate the plurality of under sets andplungers; Fig. 4 is a sectional detail showing the plunger coacting withthe punch tube to unch a hole in the stock for the eyelet; i`ig. 5 is asection in the line rc', Fig. 3; Fig. 6 is a top view detached of theguide used to position the portion of the shoe to receive the eyelet;Fig. 7 is an inner side view of the parts shown in Fig. 6, and Fig. 8 isa section in the dotted line m2, Fig. 7.

The framework shown consists essentially of a base A having risingtherefrom suitable standards A having bearings for the main shaft A2.This shaft is surrounded by a friction clutch pulley A3, of any usualconstruction and under the control of a device A that may be actuated bya treadle to start or stop the shaft.

The main shaft A2 has fast on it as herein shown two like eccentrics A5,and an eccentric A6, and said shaft has also a cam A7. Y

The cam A7 acts through a suitable lever B having its fulcrum at B toreciprocate the raceway B2 carrying the eyelets, the upper end of saidraceway being movable in a suitable hopper B3 in which the eyelets areput in bulk.

The raceway is and may be oi' usual construction, and as shown it isadapted to contain a series of grooves to deliver a series of eyelets, asuitable spring 2 at the lower end of the several compartments of theraceway coacting with each row of eyelets to maintain them on theraceway until taken therefrom positively.

The eyelets contained in the hopper are kept agitated by any usualagitator carried by a shaft B4.

The framework has rising from it a suitable stand C having a stud C thatserves as a fulcrum for two like levers C2, actuated by straps embracingthe eccentrics A5, and an intermediate lever C3 that is actuated by alink embracing the eccentric A6. The framework has an overhanging neckC4 suitably recessed to receive a block D held therein by a suitablelocking device D shown as an eccentric pin.

The block D has secured in it by suitable set screws D2 a series of uper sets D3, and a series of punches D4, eac upper set and punch havingaV central passage as a, the upper end of which terminates at a in adischarge opening for pieces of leather punched from the stock informing eyelet holes, said punchings entering a space a2 in a box a3connected by suitable screws a4, one of which is shown in Fig. 2 withthe overhanging part C4 of the framework.

Viewing Fig. 4 it will be seen that the shoulder a5 of the upper set D3acts against the reduced end or point of the eyelet, and that the lowercircular edge of the punch D1L extends sufficiently far from theshoulder a5 of the upper set to receive and sustain each eyelet as it isbeing u set.

The sharp edge of t e punch, shown as integral with the upper set,coacts with the shoulder or seat Z2 located at the base of the roundedprojection or extremity b of the plunger bx, said extremity being shapedto enter unerringly, as will be described, the large or flanged end ofan eyelet held at the lower end of the raceway, the eyelet surroundingthe plunger thus enabling the latter to always remove the eyelet fromthe raceway as the raceway is retracted. In its further movement therounded extremity ci the plunger enters and substantially iills the holein the punch D4 and centers the plunger with relation to the punch. Asthe raceway is moved backwardly in usual manner the eyelets droptherefrom and surround the plunger, and the head ends of the eyelets arearrested while the head enters the upper ends of the lower sets b2. ASthe rounded projection enters the hole in the punch the shoulders oftheplungers meet the circular cutting edges of the punches and co-actingtherewith cut clean holes in the stock for the reception of the eyelets.

Each plunger bx is extended through a hole in one of a series of undersets b2, the shanks of which are attached by suitable set screws b5 in abar b3, said bar being connected with a sliding cross head b4 by meansof a suitable set screw 5G.

The lower ends of the plungers bx are shown as having heads c thatnormally rest against a cross bar c extended through a space c2 in thecross head b4. The cross bar has suitably secured to it as by rivets c3posts c4, shown best in Fig. 3, that are extended through suitableholes, see Fig. i, in the projection or boss c5 extended from theframework A. The boss is slotted vertically to receive the cross headb4, and a suitable cover plate as d held in place by screws d maintainssaid cross head b4 in its operative position.

The lower ends of the posts c4 are slotted, and in said slots arepivoted the upper ends of links d2 in turn jointed with the outer endsof the two like levers C2 actuated by said eccentrics A5.

The cross head b4 has at its lower end, see

' Fig. 3, two ears provided with holes for the reception of a stud g,see dotted lines Fig. 1, that serves as a pivotal connection for a linkg', in turn connected with a pin g2 loose in suitable holes in the outerend ci' the lever C3 actuated by the eccentric A of the shaft A2.

The upper portion of' the boss c5 extended from the framework, supportsa plate c that partially covers the lower sets and plungers,

said plate being pivoted at one end by a stud screw c2 entering a hole ein an ear of said plate, the ear at the opposite end of said platehaving an open slot e3 that is entered by a clamp screw e4. The plate ehas applied to its inner side, see Fig. 7, by screws f narrow plates fto constitute, with the part eX of the plate e, guideways for the feetf2 of gages f 3, f 4, said feet, as herein represented, overlapping onethe other, see Figs. 7 and 8, and each foot has an inclined slot 12,said slots being directed oppositely. The narrow plates f have attachedto them by screws 18 a slotted plate f5 having a series of teeth orprojections 16 that may be engaged by the edge of a block 17 havingextended from it a threaded post 18. Said post, after passing throughone of the diagonal slots 12 in each of the feetf2 and through avertical slot 19, see Fig. 1, in the part eX of the plate e, has

applied to it preferably a washer 20, a spring 21 and a nut 20X, the nutacting through the spring to hold the post and block 17 yieldingly. Bypressing the nut 20X inwardly the post may be slid in the slot 19 andthe slots 12 to thereby move the gages f3 and f4 away from or towardeach other preparatory to the setting of a series of eyelets.

To locate the work for setting the eyelets l take hold of the work andplace the linger cooperating with the thumb holding the work against theoutside of one or the other of said gages, according to which part ofthe work, as the right or left hand portion of the top of a shoe, isbeing provided with eyelets. The work will also be grasped between thethumb and linger of the other hand, sirable because usually the worlr ispliable, and by engaging the same between both hands it is possible tosecurely hold the work taut under the sets and with the edge of the workin proper position with relation to the gages or stops as 22 or 23,according to the requirements of the work, each gage having a pluralityof such stops.

1f the eyelets are to be equidistant from the edge of the material, thesaid edge may rest against either the two faces 22 or the two faces 23,according to the distance it is desired to set the eyelets from the edgeof the material. 1f, however, it is desired to set the bottom eyelet atone edge farther from the edge of the material than the top eyelet atthat edge, then l may put the edge of the material against the face 22of the gage f i and a portion of the edge of the material at a distancetherefrom against the face 23 of the gage f3.

The gages f 3 and f 4 sustain the material in position to be punched andto receive the eyelets in the punched holes.

Each upper set is acted upon by a strong s ring 7L under the control ofa screw h. l ashers h2 are interposed between the ends of the set screwsD2 and the bodies of the top sets, and in case of strain exerted on saidupper sets or their connected punches, greater thaln they can or shouldbear, the springs will yie d.

In operation let it be assumed that the raceway has been supplied witheyelets, that the lowermost eyelet 1n each raceway groove is held by aspring 2X, that the material to be provided with eyelets is in positionwith its edge against one or the other face of the gages f3, f, and thatthe upper and lower sets are in the position Figs. l and 2. The machinewill now be started, and immediately the eccentrics A5 will cause thecross bar c to act and project the plungers to their fullest extent fromthe lower sets that said plungers may enter the row of endmost eyeets ofthe raceway, and the lever B is then actuated to withdraw the racewayand leave an eyelet surrounding each plunger.

this being de- The punches D4 occupy at all times posi:- tions in linewith the path of movement of the plungers, and as-the plungers bx andsets 7a2 continue to rise, the up er end ofthe plunger surrounded by aneye et meets the underside of the stocl, forcing the same against thelower hollow ends of the punches D4, and said plungers coacting withsaid punches punch a series of holes in the stock. During this o erationthe ends of the plungers enter slight y the open ends of the punches,and the shouldered portions of the plungers meet substantially thecircular cutting edges ofthe punches. 4 Viewing Fig. 4 it is supposedthat the series of holes have been punched in the stock, and it will beseen that an eyelet surrounds the plunger below said end, and that theplunger is in position to act as a guide for the eyelet as the end ofthe eyelet passes from the plunger into the material and about the outerside of the punch. As soon as the plungers that are moved positively bythe cross bar c, instead of being sustained by springs as usual, havecoacted with the punches to punch a series of holes in the material, theupward movement of the plungers is sto aped, as in Figs. 3 and 4, butthe crosshead L* continues to rise, causing the under sets sustainingthe heads of the eyelets to act and force the eyelets into the holesmade in the material, forcing the small ends of said eyelets against theshoulders a5 of the upper sets, thus clenching the eyelets in thematerial, and the eyelets having been set, the lower sets and plungersare lowered into their normal positions.

l have shown my invention applied to a gang eyeleter, but it is obviousthat my nvention might be practiced to advantage in an eyeleting machinehaving but one bottom and top set, a plunger, a punch and a raceway,

l believe that 1 am the iirst to provide a machine of this class withindependent gages having each an edge guiding face by which the edge ofthe material may be set in or out of line with a line intersecting allthe punches to thereby provide for inclining the line of eyelets withrelation to the edge of the material, or in other words, spreading thelowermost eyelets of the two series.

This invention is not limited to the exact shape shown for the end ofthe plunger, nor to the exact means illustrated for controlling theposition of the gages.

lt will be noticed that the punches D4 eX- tend for a considerabledistance beyond the shoulder a5 of the set D3, that acts against thesmall end of the eyelet. Elongating the punch as shown enables theeyelet being set to surround the punch and be guided thereby during theoperation of setting the eyelets. This is necessary especially when aplurality of eyelets are being set at one operation, as the long punchesact as positive guides in preventing any undue movement of the wornwhile the eyelets are being upset therein.

Pointing or rounding the extremity of the plunger greatly facilitatesand insures the unerring entrance ofthe plunger into the eyelet at theend of the raceway.

This application is a continuance of my application Serial No. 104,109,filed April 22, 1902.

Having described my invention, what I claim and desire to secure byLetters Patent is l. In an eyeleting machine, a top-set comprising a barpresenting at its end apunch constituted as a hollow tube with a cuttingedge, said bar having a shoulder at a distance from the cutting edge topermit the eyelet being set to be moved on to and to surround the punch,combined with an underset comprisingr a hollow bar, the upper end ofwhich is adapted to sustain the enlarged end of the eyelet to be set,and a spindle movable inside said bar, said spindle having near itsupper end a horizontal shoulder from which rises a protuberance havingan upwardly rounded point to readily enter the eyelet, the

horizontal portion of said shoulder coacting with the circular edge ofthe punch to cut a hole in the stock, the upwardly rounded point of thespindle above said shoulder entering said eye et and hollow tube of thepunch in advance of the cutting action of the unch, whereby said spindleis centered Wit relation to said punch.

2. In an eyeleting machine, means to present a series of eyelets, meansto punch a series of holes in material, means to set a series of eyeletsin said holes, gages to sustain the material to be punched preparatoryto receiving eyelets, said gages presenting a plurality of faces torovide for setting the eyelets at one end o' the series at a greaterdistance from the edge of the material than the eyelets at the other endof the series, and means to move said gages toward and from each otherto adapt the gages to the work to be done.

ln testimony whereof, l have signed my name to this specification, inthe presence ol two subscribing witnesses.
